Introduction

 Program "Bloch"

The program solves the Bloch Equations for magnetization:

All parameters have the conventional meaning.

The solution of this equation is:

It satisfies the following initial condition (t=0) :

The pulses rotate the magnetization vector around the x, y and z axes according to the following rotation matrices:

Program "TwoLines1D" and "TwoLineNMR"

The program simulates two-line 1D NMR spectrum with chemical exchange for the case kAB = kBA = k, T2A = T2B = 1/r, .

The case of non-reacting systems:

The case of fast reaction:
